DBInspect is a graphical database inspection tool that is still under active
development and available for free use. It provides a nice environment for
writing and executing SQL statements against relational databases,
and working with the results, as well as executing SQL scripts.

This tool is written using Java Swing and JDBC, and is portable
across many platforms and databases. It will run on any platform
that has Java installed, and will connect to any database that
has an available JDBC driver. It has been most tested on Linux and
Windows platforms, connecting to Oracle, MySQL, PostgreSQL, and SQL Server
databases.

I hope you find this tool as useful in your day to day development
as I have.
